Screening data only. This response is not a regulatory record search and must not be relied upon for any regulatory, transactional, or liability- protection purpose. Interpretation requires a qualified environmental professional.

Price: $0.10 USDC per HTTP 200. 422 and 5xx are never billed.
Coverage (v1): Federal environmental records (EPA FRS, SEMS, RCRAInfo scaffolded). Texas LPST live (TCEQ ArcGIS + Socrata, ~29,800 cases). Other states gated on demand.
Machine-readable: GET /v1/coverage · GET /v1/schema · GET /v1/health — all free.
Preferred input: A coordinate. If your agent already holds one, skip geocoding — it is cheaper and more reliable.
